In California What is the minimum hours an employer has to pay you if your sent home early?
California law doesn't mandate a number of hours an employee must be paid if sent home early for whatever reason. Instead, the state only requires employers to pay for all completed work.
So if you're sent home early during a break or before you start working, you wouldn't be entitled to any pay. Likewise, if you haven't finished your shift and you're let go, you must still be paid for all the hours you did work.
